If you’re passionate about advanced technology and ready to make a meaningful impact in telecom, this role is crafted just for you.

At Ericsson, we support your growth, offering opportunities to advance your skills while contributing to game-changing 5G/6G technologies. Here, you’ll find a supportive, innovative environment focused on quality, teamwork, and career development. Join us and help shape the future of telecom!

We are hiring a Physical Synthesis Engineer to own the synthesis flow and constraint development on high-performance, low-power SoC designs. Your primary focus will be physical-aware synthesis, floorplan-driven netlist optimization, and QoR closure — while also contributing to static timing analysis (STA) signoff as well. You will work closely with RTL design, place-and-route, and DFT teams throughout the full design cycle.

## What you will do:

Physical-Aware Synthesis (PAS)

• Execute physical-aware and floorplan-driven synthesis flows to minimize post-layout timing and congestion surprises.
• Integrate synthesis with P&R tools for early physical feedback loops — congestion-aware optimization, placement-aware buffering, and pre-CTS timing.
• Collaborate with P&R engineers on DEF/floorplan hand-off; iterate on netlist quality to reduce downstream ECO effort.
• Perform flat and hierarchical synthesis for large designs; manage partitioning and interface timing budgets.
• Perform formal or equivalence check on the netlist at block or top level.

QoR & Optimization

• Track and report key QoR metrics — timing slack, area, cell count, power — across design iterations and process corners.
• Identify and resolve synthesis bottlenecks: critical path restructuring, datapath optimization, and register retiming.
• Provide RTL coding guideline feedback to design teams to improve synthesizability and QoR from the source.
• Manage technology library characterization inputs: Liberty (.lib), LEF, and UPF/CPF for multi-voltage designs.
• Own synthesis QoR sign-off checklist and contribute to tape-out readiness reviews.

Static Timing Analysis

• Run block-level and full-chip STA using PrimeTime (PT) for timing analysis across PVT corners.
• Support MMMC (Multi-Mode Multi-Corner) timing closure; analyze and triage timing violations with P&R and synthesis teams.
• Review and validate SDC constraints developed during synthesis against post-layout STA results.
• Contribute to clock domain crossing (CDC) checks and timing exception audits during signoff.

## The skill you bring:

• 5+ years in physical synthesis or logic design implementation
• Expert-level use of Fusion Compiler
• Strong SDC constraint authoring and management skills
• Experience with physical-aware synthesis flows and P&R hand-off
• Working knowledge of STA (PrimeTime)
• Proficiency in Tcl; Python scripting a strong plus
• At least one tape-out on 7nm or below

## Nice to have:

• Familiarity with low-power methodologies (UPF/CPF, multi-Vt, clock gating)
• Understanding of PTPX-based power analysis flows
• DFT synthesis experience (scan, BIST, boundary scan)
• Familiarity with congestion-aware and timing-driven P&R closure

EDA Tools & Environment

• Design Compiler, Fusion Compiler, Synopsys PrimeTime, Formality, Tcl/Python.
